Description

Die Erfindung bezieht sich auf einen Wärmetauscher für zwei Medien, insbesondere ein Ladeluftkühler für eine Brennkraftmaschine, mit in einem geschlossenen Gehäusemantel angeordneten Kühlerblock und daran gegenüberliegend anschließenden Räumen zum Verteilen bzw. Sammeln der innerhalb des Kühlerblockes quer zueinander durch Kanäle oder dergl. strömenden beiden Medien, wobei die beiden Räume für das Kühlmedium durch seitlich am Gehäusemantel angebrachte Verteiler- bzw. Sammelkästen gebildet und die Räume für das zu kühlende Medium innerhalb des Gehäusemantels beiderseits des Kühlerblockes angeordnet sind.The invention relates to a heat exchanger for two media, in particular a charge air cooler for an internal combustion engine, with a cooler block arranged in a closed housing jacket and adjoining spaces for distributing or collecting the two media flowing transversely through channels or the like within the cooler block, the two spaces for the cooling medium being formed by distributor boxes or sockets attached to the side of the housing shell, and the spaces for the medium to be cooled are arranged on both sides of the cooler block within the housing shell.

Aus der DE-PS 20 37 873 ist ein Wärmetauscher bekanntgeworden, der in einem zylindrischen Gehäuse mittig ein axial verlaufendes Rohrbündel aufweist, das zwischen zwei Leitwänden liegt. Die einzelnen Rohre sind beiderseits in Rohrböden gehalten, welche den Gehäusemantel seitlich abdichten. Zum seitlichen Abschluß des Gehäusemantels dienen an dessen Stirnseite befestigte, nach außen gewölbte Dekkel, deren mit den Rohrböden gebildeten Innenräume dem durch das Rohrbündel zu leitenden Medium als Verteiler bzw. zum Umlenken dienen. Für das quer durch das Rohrbündel zu führende Medium sind am Gehäusemantel für dessen Zu- und Ablauf radiale Rohrstutzen vorgesehen, die mit je einem durch die inneren Leitwände gegenüber dem Rohrbündel abgegrenzten Verteiler- bzw. Sammelraum in Verbindung stehen. Bei diesem bekannten Wärmetauscher ist der Wärmeaustausch zwischen den beiden Medien nur im Bereich der gebündelten Rohre möglich, während der Gehäusemantel an diesem Vorgang keinen Anteil hat. Vielmehr wird die vom Gehäusemantel aufgenommene Wärme nach außen abgestrahlt, so daß gegebenenfalls ein besonderer Berührungsschutz bzw. eine thermische Isolation erforderlich ist.From DE-PS 20 37 873 a heat exchanger has become known which has an axially extending tube bundle in the center of a cylindrical housing, which lies between two guide walls. The individual tubes are held on both sides in tube plates, which laterally seal the housing jacket. For the lateral closure of the housing jacket, there are attached, outwardly arched covers on its end face, whose inner spaces formed with the tube sheets serve as a distributor or for deflecting the medium to be conducted through the tube bundle. For the medium to be led across the tube bundle, radial tube stubs are provided on the housing jacket for its inlet and outlet, each with one through the inner guide walls opposite the tube bundle delimited distribution or collection space. In this known heat exchanger, the heat exchange between the two media is only possible in the area of the bundled tubes, while the housing jacket has no part in this process. Rather, the heat absorbed by the housing jacket is radiated to the outside, so that special contact protection or thermal insulation may be required.

Der Erfindung liegt die Aufgabe zugrunde, einen Wärmetauscher der eingangs umrissenen Art zu schaffen, bei dem mit einfachen Mitteln ein möglichst guter Wärmeübergang von einem Medium zum anderen erzielt wird. Außerdem soll die vom Gehäusemantel aufgenommene Wärme möglichst gering sein, um Verformungen desselben sowie unerwünchte Abstrahlungen zu vermeiden.The invention has for its object to provide a heat exchanger of the type outlined in which the best possible heat transfer from one medium to another is achieved with simple means. In addition, the heat absorbed by the housing jacket should be as low as possible in order to avoid deformation thereof and undesired radiation.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der die Räume zum Verteilen und Sammeln des zu kühlenden Mediums begrenzende Teil des Gehäusemantels durchgehende Hohlräume aufweist, die in den KÜhlmittelstrom eingeschaltet sind.The object is achieved in that the part of the housing jacket delimiting the spaces for distributing and collecting the medium to be cooled has continuous cavities which are switched into the coolant flow.

Durch diese Maßnahmen wird dem zu kühlenden Medium in den dem Kühlerblock vor- bzw. nachgeschalteten Räumen zum Verteilen bzw. Sammeln des Mediums zusätzlich Wärme entzogen, so daß sich eine bessere Kühlwirkung ergibt. Ferner wird eine unzulässig starke Erwärmung des äußeren Gehäusemantels vermieden.These measures additionally remove heat from the medium to be cooled in the rooms upstream or downstream of the cooler block for distributing or collecting the medium, so that there is a better cooling effect. Furthermore, excessive heating of the outer casing is avoided.

Zur Vereinfachung des Aufbaues und zur Vermeidung unzulässiger thermischer Spannungen ist in Weiterbildung der Erfindung vorgesehen, daß der Gehäusemantel auch in seinem den Kühlerblock aufnehmenden Bereich in den Kühlmittelstrom eingeschaltete Hohlräume aufweist.In order to simplify the structure and to avoid impermissible thermal stresses, a further development of the invention provides that the housing jacket also has cavities switched into the coolant flow in its area receiving the cooler block.

Eine konstruktiv günstige Lösung ist dadurch gegeben, daß der vom Kühlmedium durchströmte Gehäusemantel aus zwei U-förmigen Formteilen besteht, die zu einem den Kühlerblock aufnehmenden, im Querschnitt kastenförmigen Bauteil miteinander verschweißt sind.A structurally favorable solution is provided in that the housing jacket through which the cooling medium flows consists of two U-shaped molded parts which are welded to one another to form a cross-sectionally box-shaped component which receives the radiator block.

Eine weitere Vereinfachung des Aufbaues eines Wärmetauschers bei gleichzeitiger Gewichtsersparnis ergibt sich dadurch, daß der Gehäusemantel sowie der Kühlerblock in Sandwich-Bauweise ausgeführt sind.A further simplification of the construction of a heat exchanger while at the same time saving weight results from the fact that the housing jacket and the cooler block are constructed in a sandwich construction.

Der in den Fig. 1 und 2 gezeigte Wärmetauscher stellt einen Ladeluftkühler für eine Brennkraftmaschine dar, bei dem Wasser als Kühlmedium verwendet wird. Der Ladeluftkühler hat einen kastenförmigen Gehäusemantel 1, der gemäß Fig. 1 aus zwei U-förmigen Formteilen 2 und 3 zusammengefügt ist. Die beiden Formteile 2 und 3 sind in Sandwich-Bauweise entweder in der gezeigten U-Form hergestellt oder in einem besonderen Arbeitsgang an gegenüberliegenden Enden so nach innen umgebogen, daß sie zusammengefügt einen geschlossenen Kastenquerschnitt gemäß Fig. 1 ergeben. Der Gehäusemantel 1 besteht aus einem äußeren Blech 4 und einem dazu mit Abstand befindlichen inneren Blech 5, zwischen denen ebenfalls mit Abstand voneinander stabförmige, im Querschnitt vorzugsweise quadratische Elemente 6 angeordnet sind. Zwischen den einzelnen Elementen 6 verbleiben durchgehende Hohlräume 7 für den Durchtritt des Kühlmittels.The heat exchanger shown in FIGS. 1 and 2 represents a charge air cooler for an internal combustion engine, in which water is used as the cooling medium. The charge air cooler has a box-shaped casing shell 1, the ig according F. 1 is assembled from two U-shaped molded parts 2 and 3. The two molded parts 2 and 3 are made in a sandwich construction either in the U-shape shown or in a special operation at opposite ends so that they are joined together result in a closed box cross section according to FIG. 1. The housing jacket 1 consists of an outer plate 4 and an inner plate 5 which is spaced apart therefrom, between which rod-shaped elements 6 which are preferably square in cross section are also arranged at a distance from one another. Continuous cavities 7 for the passage of the coolant remain between the individual elements 6.

Zum Biegen der Formteile 2 und 3 kann es zweckdienlich sein, wenn das äußere Blech 4 vor dem Biegen an der Biegekante durchtrennt wird. Nach dem Arbeitsvorgang wird dann der beim Biegen an der Biegekante entstehende Spalt 8 durch ein aufgesetztes Winkelblech 9 gemäß Fig. 3 abgedichtet.For bending the molded parts 2 and 3, it may be expedient if the outer sheet 4 is cut at the bending edge before the bending. After the working process, the gap 8 which arises during bending at the bending edge is then sealed off by an angle plate 9 as shown in FIG. 3.

Innerhalb des kastenförmigen Gehäusemantels 1 befindet sich ein an diesen eng anschließender Kühlerblock 11, der in gleicher Sandwich-Bauweise hergestellt ist, wie der Gehäusemantel 1. Durch den Kühlerblock 11 durchgehende Kanäle für die zu kühlende Ladeluft sind mit 12 bezeichnet. Oberhalb und unterhalb des Kühlerblockes 11 sind im Gehäusemantel 1 Räume 13 bzw. 14 angeordnet, die sich über die Länge und Breite des angrenzenden Kühlerblockes 11 erstrecken. Der obere Raum 13 ist mit einem Lufteintrittsstutzen 15 verbunden, der im Formteil 2 befestigt ist. Dieser Raum 13 dient zum Verteilen der angesaugten Ladeluft auf die Fläche des angrenzenden KÜhlerblocks 11. Der untere Raum 14 steht mit einem ebenfalls im Formteil 2 befestigten Luftausgangsstutzen 16 in Verbindung und dient zum Sammeln der den Kühlerblock 11 verlassenden Ladeluft, bevor diese in den Stutzen 16 eintritt.Inside the box-shaped housing jacket 1 there is a cooler block 11 closely connected to it, which is manufactured in the same sandwich construction as the housing jacket 1. Channels for the charge air to be cooled, which pass through the cooler block 11, are designated by 12. Above and below the radiator block 11, spaces 13 and 14 are arranged in the housing shell 1, which extend over the length and width of the adjacent radiator block 11. The upper space 13 is connected to an air inlet connector 15 which is fastened in the molded part 2. This space 13 is used to distribute the sucked-in charge air onto the surface of the adjacent radiator block 11. The lower space 14 is connected to an air outlet connection 16 also fastened in the molded part 2 and is used to collect the charge air leaving the cooler block 11 before it reaches the connection 16 entry.

An den Gehäusemantel l schließen sich gemäß Fig. 2 beiderseits je ein Kasten 18, 19 an, die sich über die volle Höhe und Breite des Gehäusemantels 1 erstrecken. Die Kästen 18, 19, die für die Verteilung und Ableitung des Kühlwassers dienen, sind mit je einem Stutzen 20 bzw. 21 für den Zulauf bzw. den Ablauf des Kühlwassers ausgestattet. Bei entsprechender Ausbildung kann einer der Kästen 18 bzw. 19 auch als Umlenkdeckel dienen.According to FIG. 2, a box 18, 19 adjoins the housing jacket 1 on both sides, which extends over the full height and width of the housing jacket 1. The boxes 18, 19, which are used for the distribution and discharge of the cooling water, are each equipped with a nozzle 20 and 21 for the inlet and outlet of the cooling water. With appropriate training, one of the boxes 18 and 19 can also serve as a deflection cover.

Das Kühlwasser tritt durch den Stutzen 20 in den Kasten 19 ein und wird hier auf die einzelnen Hohlräume 7 im Kühlerblock 11 sowie im Gehäusemantel 1 zum Durchströmen derselben verteilt. Das sich im Raum 18 nach dem Durchströmen der genannten Hohlräume 7 sammelnde Kühlwasser fließt durch den Stutzen 20' wieder in den Kühlkreislauf der Brennkraftmaschine. Die zu kühlende Ladeluft gelangt durch den Stutzen 15 i.n das Innere des Wärmetauschers, wo nicht nur im Kühlerblock 11 sondern auch in den Räumen 13 und 14 eine Abkühlung der Ladeluft erfolgt. Die gekühlte Ladeluft strömt schließlich durch den Stutzen 16 zu den Zylinderköpfen einer nicht dargestellten Brennkraftmaschine.The cooling water enters through the nozzle 20 into the box 19 and is distributed here to the individual cavities 7 in the radiator block 11 and in the housing jacket 1 for flow therethrough. The cooling water that collects in space 18 after flowing through said cavities 7 flows back through connector 20 ′ into the cooling circuit of the internal combustion engine. The charge air to be cooled passes through the connector 15 in the interior of the heat exchanger, where the charge air is cooled not only in the cooler block 11 but also in the rooms 13 and 14. The cooled charge air finally flows through the connector 16 to the cylinder heads of an internal combustion engine, not shown.

Durch diese Ausbildung eines Ladeluftkühlers ergibt sich bei einem relativ geringen Gewicht eine hohe Formstabilität, was sowohl in bezug auf mechanische Beanspruchungen als auch auf den Ladeluftinnendruck gilt. Außerdem werden thermische Spannungen dadurch vermieden, daß die gesamte Außenwandung des Gehäusemantels ständig vom Kühlwasser durchströmt wird.By this design of an L adeluftkühlers a high dimensional stability, as well as applies with respect to mechanical stress on the charge air pressure is obtained at a relatively low weight. In addition, thermal stresses are avoided by the cooling water continuously flowing through the entire outer wall of the housing shell.

Der in Fig. 4 im Querschnitt gezeigte Wärmetauscher 21 ist als Ladeluftkühler an die Luftzuführung 22 zum Zylinderkopf einer Brennkraftmaschine angeschlossen. Der Ladeluftkühler ist von einem Gehäuse 23 umschlossen, das infolge einer mittigen Biegung 24 einen im wesentlichen U-förmigen Querschnitt aufweist, wobei an den einen Schenkel 25 der U-Form der Eintritt der Ladeluft in den Kühler durch einen Stutzen 26 erfolgt. Ein am anderen Schenkel 27 des Kühlers sitzender Stutzen 28 führt die gekühlte Ladeluft zur Brennkraftmaschine. Als wesentliches Tragelement des Ladeluftkühlers 1 dient der Stutzen 28, der sehr kräftig ausgebildet ist und über einen Flansch 29 mit der Luftzuführung 22 verschraubt ist. Ein das Gehäuse 23 bildender doppelwandiger Mantel 30 ist insgesamt in Sandwich-Bauweise ausgeführt und zweckmäßig aus zwei für sich U-förmigen Schalen zusammengefügt. Im Gehäuse 23 des Ladeluftkühlers 21 befindet sich in jedem der Schenkel 25 und 26 je eine Hälfte eines zweiteiligen Kühlerblockes 31, 32, die ebenfalls in Sandwich-Bauweise ausgeführt sind. Die dabei sowohl im Gehäusemantel 1 als auch in den Kühlerblöcken 31 und 32 verbleibenden durchgehenden Hohlräume 34 sind für den Durchtritt des Kühlmittels vorgesehen, welches somit quer zur Ladeluft den Kühler durchströmt. Ein im Strömungsverlauf zwischen den beiden Kühlerblöcken 31 und 32 im Innern der Biegung 24 befindlicher freier Raum 35 dient als Umlenkraum für die den Kühler durchströmende Ladeluft. Im Umlenkraum 35 können bei Bedarf zusätzlich Leitbleche und/oder vom Kühlmittel durchströmte Kühlrippen angeordnet sein. Dieser Ladeluftkühler hat durch die gegebene U-Form eine sehr kompakte Bauweise, so daß er wenig Bauraum beansprucht.The heat exchanger 21 shown in cross section in FIG. 4 is connected as a charge air cooler to the air supply 22 to the cylinder head of an internal combustion engine. The charge air the cooler is enclosed by a housing 23 which, as a result of a central bend 24, has an essentially U-shaped cross section, the charge air entering the cooler through a nozzle 26 on one leg 25 of the U shape. A connector 28 located on the other leg 27 of the radiator leads the cooled charge air to the internal combustion engine. The connecting piece 28, which is of very strong design and is screwed to the air supply 22 via a flange 29, serves as an essential supporting element of the charge air cooler 1. A double-walled casing 30 forming the housing 23 is designed as a sandwich construction and is expediently assembled from two U-shaped shells. In the housing 23 of the charge air cooler 21 is in each of the legs 25 and 26 one half of a two-part cooler block 31, 32, which are also designed in sandwich construction. The continuous cavities 34 remaining both in the casing shell 1 and in the cooler blocks 31 and 32 are provided for the passage of the coolant, which thus flows through the cooler transversely to the charge air. A free space 35 located in the interior of the bend 24 in the flow course between the two cooler blocks 31 and 32 serves as a deflection space for the charge air flowing through the cooler. If necessary, additional baffles and / or cooling fins through which the coolant flows can be arranged in the deflection space 35. This intercooler has a very compact design due to the given U-shape, so that it takes up little space.

Der in Fig. 5 gezeigte Ladeluftkühler 37 hat grundsätzlich die gleiche Bauweise wie der Ladeluftkühler 21 in Fig. 4. Der Ladeluftkühler 37 hat lediglich eine andere Querschnittsform, wobei im Gehäuse 38 durch eine Biegung 39 eine Abwinklung von 90° vorgesehen ist. Hierdurch ergibt sich im Innern des Kühlers ein Umlenkraum 40, in dem die Ladeluft in Strömungrichtung hinter dem Kühlerblock 41 um 90° umgelenkt wird, bevor die Ladeluft durch den anderen Kühlerblock 42 zur Brennkraftmaschine gelangt. Bei dieser Ausführung eines Ladeluftkühlers ist der Gehäusemantel 43 ebenfalls in seiner ganzen Erstreckung mit durchgehenden Hohlräumen 44 zum Durchströmen des Kühlmittels versehen. Die in Fig. 5 gezeigte abgewinkelte Form eines Ladeluftkühlers 37 eignet sich insbesondere für solche Brennkraftmaschinen, deren Zylinder in V-Form angeordnet sind.The charge air cooler 37 shown in FIG. 5 basically has the same construction as the charge air cooler 21 in FIG. 4. The charge air cooler 37 only has a different cross-sectional shape, with a bend 39 in the housing 38 an angle of 90 ° is provided. This results in a deflection chamber 40 in the interior of the cooler, in which the charge air is deflected by 90 ° in the flow direction behind the cooler block 41 before the charge air reaches the internal combustion engine through the other cooler block 42. In this embodiment of a charge air cooler, the housing jacket 43 is also provided in its entire extent with continuous cavities 44 for the coolant to flow through. The angled shape of an intercooler 37 shown in FIG. 5 is particularly suitable for internal combustion engines whose cylinders are arranged in a V shape.
